EKG Interpretation Basics
First degree heart block - Type of heart block with prolonged PR interval.
Heart block - Delay or interruption in the electrical conduction system.
Isoelectric - Flat segment of the EKG representing resting heart cells with no electrical activity.
Mitral Valve - Enables blood flow from left atrium to left ventricle.
P wave - Represents atrial depolarization, should be less than 0.12 seconds.
PQRST Complex - Depolarization and repolarization sequence in heart cells.
PQRST complex - Represents the electrical conduction system from SA node to Purkinje fibers.
PR interval - Time for electrical signal to travel from atria to AV node, important in determining
heart block.
PR segment - Demonstrates the delay created by the AV node for atria to empty into ventricles.
Pulmonary Vein - Carries oxygenated blood from lungs to left atrium.
Pulmonic Valve - Facilitates blood flow from right ventricle to pulmonary artery.
Purkinje fibers - Conduct electrical signals to cause ventricular contraction.
